DEVICE FOR COOLING AND LUBRICATIWG BEARINGS.

Application filedMay 24, 1915.

,To alt 107L011}, it may concern Be it known that I, Gnonon E. Ponmor, a citizen of the United States, residing at ,fzlouth Lawrence, the county of Essex and State of ltlassachusetts, have invented new and useful Improvements in Devices for Cooling and Lubricating Bearings, of which the following is a specification.

This invention relates to devices for cooling and lubricating bearings that have become overheated, and it has particular reference to a device for cooling and lubricating hot boxes of railroad cars.

The invention has for its object to produce a simple and eilective device embodying a tank having compartments containing water and lubricating oil and valved connections between said compartments and the bearing that is to be cooled and lubricated.

A further object of the invention is to produce a simple and effective device of the class described wherein the flow of lubricating oil will be automatically started when the flow of water or other cooling liquid has been exhausted.

A. further object of the invention is to produce a simple and effective device of the character described which may be readily applied and used in connection with the trucks of railroad cars.

With these and other ends in view which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawing has been illustrated a simple and preferred form of the invention, it being, however, understood, that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claims may be resorted to when desired.

The drawing represents a side elevation, partly in section, showing the invention ap plied to a railroad car truck.

The truck 15 is provided with the customary boxes 16 affording bearings for the axle 17 carrying the wheels 18. A tank 19 is supported above the truck by means of straps or hangers 20 connected with the car body 21 or in any other convenient manner.

Patented Dec. 28, 1915. serial no. 30,187. I

This tank which may be of any desired shape and dimensions is provided with a partition 22 forming separate compartments 2;, 2 1, respectively, containing cooling liq.- uld, such as water, and lubricating oil, the compartment for the cooling liquid being obviously the larger of the two. Each com partment has been shown as being provided with a filling tube 25 having a lid or closure 26 which may be 01" any description. The lubricant compartment 2 has an outlet tube or duct 27 opening in the compartment 23 where it is provided with an obstructing valve 28 voperable by means of a lever 29 which is fulcrumcd on a support 30 and which carries a float 31. When the float 31 is in a raised position, as seen in full lines in the drawing, the valve 28 will be seated; when the float 31 gravitates to a lowered position, as seen in dotted lines, the valve will be unseated, and the outlet through the duct 27 will be unobstructed. lhe compartment 23 is connected with the bearing boxes 16 by ducts 32 which may include sections 33 of rubber hose or other flexible connections. Each duct 32 has a manually operable valve 34 whereby fiow of liquid therethrough may be controlled. It is obvious that the compartment 23 may be connected with one or more boxes or bearings without regard to the respective locations of such bearings and the tank 19, except that the latter should occupy a relatively elevated position to insure the gravitational flow of liquid.

When a hearing has become overheated the valve 3% pertaining to the duct which connects such bearing with the compartment 23 is opened, permitting the cooling liquid to pass to the bearing which will be thereby cooled, the liquid overflowing, as is well understood. While the contents of the com partinent 23 is being exhausted the valve 28 will gradually be unseated, causing the tow of the cooling liquid to be succeeded by the How of lubricant which, being applied to the bearing after the latter has been cooled, will now be effective to lubricate the same. If desired, the valve 84 may now be partly closed for the purpose of regulating the flow of lubricant and conserving the same.

Lubricant applied to an overheated hearing serves no good purpose because it is liable to be scorched or even ignited. By the presentinvention the bearing is first cooled and the flowof lubricant automatically follows.

Having thus described the invention, what is claimed as new, is

1. A cooling and lubricating device for hot boxes comprising a compartment for cooling liquid, a compartment for lubricant, an outlet from the lubricant compartment opening into the cooling liquid compartment, an obstructing valve for said outlet, means for unseating said valve operative by the exhaust of the contents of the cooling liquid compartment, and a valved connection between the last named compartment and the box to be cooled and lubricated.

2. In a device of the class described, compartments for cooling liquid and for lubricant, a duct connecting said compartments, a

bearing box, a valved connection between said box and the cooling liquid compartment, means for obstructing the How of llquid through the duct between the two compartments, and means for controlling the bearing box, a container having compartments for cooling liquid and for lubricant, an outlet from the lubricant compartn'icnt opening into the cooling liquid compartment, a lever fulcrumed in the last named compartment, a connection between one arm of said lever and the obstructing valvc. a float carried by the other arm of the lever, and a valved connection between the cooling liquid compartment and the box to be cooled and lubricated.

at. In a device of the class described, sources of supply of cooling liquid and of lubricating material, a valved connection between the cooling liquid source and a bearing to be treated, and mechanism whereby the opening of said valved connection will permit the flow of cooling liquid and lubricating material successively therethrough.

In testimony whereof I aflix my signature in presence of two witnesses.
